MSI R4890 Cyclone OC
 

The Cyclone OC gets a bit of an overclock, but nothing terribly substantial: it gains a 30MHz gain to the core, while the memory runs at the same speed. The cooler looks like it could handle more, so this seems a bit tame for an OC -- for comparison, the recently reviewed VisionTek HD 4890 OC ran at blistering 950MHz. http://www.neoseeker.com/Articles/Ha...iR4890cyclone/
